vBeit knownthat', CARL VFinn)"lllfonr,

a .citizen of the United States; and "aresident of Chicagoin the. county ofCool and State of lllinois,l have invented 'a new Aand useful ImprovementV in lRims for "Vehicle and "exact description. y y w My inventionrrelates' to improvementsm rims for vehicle'tires, andit consists in the combinations; 'constructions,''andl arrangements herein describedand` claimed. ,-7 An 'object'fio'fvmy"'inveition'v is'to. 'provide a rim of the characterdes'cribed from which quickly and easily efof specifi'ltols' or Tires. of which thefollowing is a full, clear,

` removed viwithut i the :rim'tools. ',l l u n A further bj'ect'of my ,invention -to provi de a device "of the' character# described in which the retaining ring isconstructed of two parts which arearrlan'ged 'to be'drawn toward. thel center of the 'vehiclejwlieell'by means of' bolts andnot sprung"overftheyehicle rim as in the ordinary .type :offretaining rings in presentuse. :j y.

A further object ofjm' invention'is'to y provide a deviceof the character described which precludes entirely the necessity' of hammering the retaining ringV to either set it in place upon the rim or to remove it from the rim. vIn the ordinary type of rctaining ring,`fthe ring is lfrequently battered by the necessary use of a mallet or the like to free the ring from its close engagement with the wheel rim.` It is apparcnt that such vmutilation (of the riugfoccasions a great deal of diiliculty in thesub .sequent application of the ring to the rim. further object of my invention is to provide u device of the character described thatis extremely simple in construction, that is durable, and thoroughly practical for the purpose intended.

l@ther objects and advantages will appear in the following` specification, and the inovel featiues of the invention will be particularly pointed out in the appended claim. e My invention is illustrated in the accompanving drawings forming part of this -applie/ation.` in which I Figure l is a'front elevation of an embodiment of my invention with a-portion of the vehicle tire shown upon the rim,

The rim section 2 is provided'wi'th 'al substantially hori- "zontal portion 3', upon/the outer" peripheral wall l of lwhich a 'vehicle'tire casing I5. is mounted.y The rim section 2 is provided with an integral sidewall 6 at the peripheral edge thereof, andan inwardly extending ilange 7 disposed adjacent to the other peripheral edge. This iiange 7 is angular in form and provides intermediate the adjacent wall portions 8 and 9 thereof, a groove 10. The removable retaining ring 1l is provided with an inward radially extending iiange l2 and is arranged to be received with the flange l2 in the groove l0, thereby preventing lateral movement ofthe ring ll.

The retaininffl ring ll as may be seen in Figure 1,'is constructed of two identical parts 13 vand' ifi-5 which when placed with their ends abutting. forma. perfect annulus. y So' far-the construction. is identical with the ordinary type of tire retaining construction witlithet exception-that the retaining ring l1 is composed of two parts whereas the ordinary `retaining ring is merely a split ring'lwhicli must be" actually sprung to occasion its lodgement in theigroove 10.

The retaining' ring in my present invention differs further from the ordinary type of retaining ringin that the parts 13 and 14 of the ring 11 are provided with three outwardly extending lugs 15 fand 16. The

lugs 1`5'-are disposed adjacent the ends 17 of theparts 13 and 14 and the lug 16 is dis- 5 posed intermediate the length of each part Asubstantially at the --mid point fthereof. T his construction may be more fully understood b y an inspection of Figure 3 in which the lug 16 is shown in section.

The outer side Wall 18 of the flange 7 of the rim 2 .isprovided with. six outwardly eX- tending lugs V15a and 16, the lugs. 15L being .in registretion Awith the lugs 15 on the ring 1 ;1, end ,the lugs- A16a inv registration ,with the 15 lugs 16 of the ring 11.
